Adrien is slowly coming up to speed on prior events and oh ... planetary destruction, that sounds familiar.

He'll be against throwing Bruce (though he doesn't know the man) and/or the Captains under the bus. That's now how crew works ffs.

He would genuinely try to find a solution that doesn't involve sacrificing crew/captains and lets all parties walk away in peace. However, if that seems to be impossible, he'd support -and volunteer- to go for a face to face meeting as a delay tactic to allow the Moira to prepare to defend herself.

If the Caducus Primary would allow them on their ship, he'd advocate that route and also toss out the possibility of trying to strip the ship of any/all information about what set Caducus Primary off at the Moira during their previous (not the current crew's) visit. The one that got them thrown off the planet in the first place.

Hey, if they have to blow their enemies to space dust, let's get some information first!

Adrien will also suggest that a compromise might be to offer to hold a trial, so the C-Primes can air their grievances and apologies might be offered.

However, given the light of some information ... he might suggest that the prepare for the worst. IDK, depends upon how the leaders lead.
